Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	27,458,121.60 Kilowatt-hours	93,687.11 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	62,332,082.30 Kilowatt-hours	212,677.06 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	208,895 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

515,259.18 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

180,131.95 Gross square meters

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	July 1, 2005	June 30, 2006

A brief description of when and why the energy consumption baseline was adopted:

2006 is the year the college established its Sustainable Use of Resources Policy.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.85 MMBtu per square meter	1.70 MMBtu per square meter
Baseline year	1.68 MMBtu per square meter	2.72 MMBtu per square meter

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

37.58

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

The Power Shift initiative promotes energy conservation practices and engages employees to participate and track their personal energy consumption and participate in annual energy reduction challenges through NWEI Eco Challenge.

As part of our Strategic Energy Management Program (check in with Farid)

A brief description of energy use standards and controls employed by the institution:

All buildings at PCC are operated with DDC temperature controls and all buildings are operated on schedules based on occupancy. Our DDC system is accessible through a graphic front end that allows us to schedule the operation of major equipment based on occupancy and optimal start programs so that the space temperatures are achieved for occupancy using the least amount of energy.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

LEDs are used to replace older lighting as we work to phase these out across the district. Recessed can lighting manufactured by HALO make up the bulk of the inside lighting, at 14 watts per fixture. Parking lot lighting is also being upgraded to LEDs made by BETA.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Passive solar features such as vertical sun shades that protect against late afternoon sun and horizontal shades that protect against early afternoon sun help keep new LEED certified buildings cool. Overhangs protect against solar heat gain while carefully placed windows let in natural light, saving electricity. The Newberg Center, a Net Zero Building uses natural ventilation and fans to efficiently cool the building. When open, louvers on the exterior wall of the building draw in fresh air from outside and turbines spin to help pull hot air out of the building. Exposed concrete in the building acts as thermal mass, helping maintain even building temperatures all year long.

A brief description of co-generation employed by the institution:

We formerly had cogeneration fuel cells powered by natural gas are used at the Sylvania campus, but these are no longer in use at the indoor pool.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

Upgrades of appliances dictates choosing Energy Star options when applicable, and our replacement schedule factors in when the energy use of older, less efficient models warrants replacement.
